Assume that two marbles are drawn without replacement from a box with 1 blue, 3 white, 2 green, and 2 red marbles find the probability that the second marble is white. given that the first marble is blue oa. 3 64 o b. 3 o c. 3 7 o d. 3 56

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: b
